DRY CLOSET.

Specification of Letters Patent.

Patented Dec. 17, 1918.

Application :tiled April 3, 1918; Serial No. 226,434.

To all lwhom t may concern:

Be it known that I, FRANK PAVLIK, Jr., a citizen of the United States, residing at Westminster, in the county of Adams and State of Colorado, have invented certain new and useful Improvements in Dry Closets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 'it appertains to make and use the same.

This invention relates to improvements in dry closets of the indoor chemical type, and especially to that class which are detachably associated with an air outlet conduit for ventilating purposes, coperating with the action of a suitable chemical or the like, preferably in liquid form, introduced into the fecal container, for relieving its contents of foul odors and other unsanitary conditions.

As the general aims and advantages of this type of closets are fully understood, it will be unnecessary to further initially refer -to the objects of the present improvements,

which will be clearly apparent as incidental to the following disclosure, although by way of emphasis it may be said that the invention is more peculiarly adapted for use on the farm, homestead, or other outlying localities, where the usual water flushing closets may not be feasibly installed, owing to lack of water facilities and sewerage systems.

With these prefacing remarks, the invention consists of the combination and structural arrangement of parts as hereinafter described, the-essential features ofnovelty being more succinctly set forth in the appended claims, but to more clearly understand the invention, reference will now be had to the -accompanying drawings illustrating a preferred embodiment of the same, in which drawings like reference characters designate the same parts in the several views, of Which- Figure 1, is an elevational view of the 1nstalled closet, the upper portion of the container receptacle being broken away and the seat therefor being shown in section; Fig. 2, is a detail sectional view through the coupling connections, being taken `along the plane of the line 2 2 of Fig. 1, and showing the upper portion of the base standard in .the coupling, with a front elevation; and Fig. 3, is a detachably associated detail view` of the coupling connections.

10 designates the closet proper, which is 4 for emptying and washing y of the container 10, and this seat is provided with the usual hinged closurer lid 15.

The container, at its upper rear portion, has a foul air outlet 16, from which projects an upper or topping member-of a two-part coupllng of a peculiar structure, which coupling forms one of the essential features 0f the present invention.

This upper or topping member of the coupling, at the end where it leads from the foul mation, asat 17, and toward its projecting outer end the underneath wall thereof is cut away to provide an overlapping upwardly convex tongue portion 18, the underneath edge faces of which incline downwardly, as at 19, from its forward edge face 20 to its joinder with the cylindrical portion 17, forming the upwardly concave shoulder `21.

The tongue portion 18 is apertured at 22, through its upper wall, and the whole ele` ment coperates with a complementary oppositely disposed lower receiving member of scarf-like joinder, the receiving member being similarly shaped although in reverse disposition, and the corresponding parts of which are designated by the numerals 23, 24, 25, 26 and 27, respectively, while the top surface of the cylindrical portion thereof is provided with a projecting lug 28, preferably tapered or conical, adapted to air outlet 16, is of cylindrical fory y lit within the aperture 22 i' of the tongue portion 18, providing center` ing and interlocking means therebetween.

These coupling members, therefore, provide concavo-convex tongue portions of overlapping trough-like formation, and the cylindrical portion 23 of the lower member ter- `minates in an elbow arm 29, which in turn Atelescopes with a section 30 of a vent pipe leading,in any suitable manner, to the atmosphere exteriorly of the building where the closet is installed.

Another important feature of my invention resides in the structural formation of the base standard 31 and the manner of adjustably securing the lower coupling member thereto, with its `vertical elbow arm 29 in telescoping alinement with the vent pipe section 30, thus compensating for any unevenness of the floor relatively to the positions ofthe container 10 and the base standard, and hence the proper positioning of the lower and topping coupling members, so that they will fit each other snugly in readily separable and attaching relations.

The lower body of this base standard is preferably conical, being provided at its bottomwith a securing flange to rigidly fix thesame to the floor orother support, but it is to be especially noted that its upper end 32 is of cylindrical formation and of a diameterslightly greater than'that of the vertical elbow yarm1 29 of the lower coupling member.

The lower forward wall 'of this cylindrical top fportion`32 is cutawayto provide an lelongated opening or slot 33, adapted to freely receive the elbow portion of the lower vcoupling member. From the upper end of this slot,the` cylindrical portion 32 is slit or separated to its top edge face, as indicated at 34, and adjacent thereto the contiguously disposed parallel vertical ears 35, or lugs,project laterally therefrom, being adapted to be drawn together or eased up by the tightening bolts 36 0r their equivalent.

In assembling the parts, the elbow section 29 of the lower coupling member is inserted upwardly through the slot 33, when it may be clamped within the ycylindrical portion 32, in properly adjusted position,

the bolt 'elements It will be evident that, when the container 1.0 is to be placed in set up position,

the cylindrical portion 17 of the upper coupling; member will lit snugly within the vtrough-like tongue portion 24 of the lower vcoupling member, and reversely the tongue portion 18 of the upper member will like- `Wisefit snugly over the cylindrical portion 23 of the lower member, while the lug 28 enters the aperture 22 andthe coupling elements are readily interjoined and securely interlocked against ylat-eral displacement, by

"simplylowering the container receptacle,

with the upper coupling member registerin'g with and fitting down over the lower one.

' iAsin similar types of closets, I also em- 4vploya suitable chemical mixture in the container, and the noxious odors and gases, not entirely thrown l down or killed by the ltion with the usual container air outlet adapted -slot' terminating in a topof the head, and springy through said head, with its vertical arm pro- 4tion with said vent pipe,

of forced draft,-soinetimes used in ventilating systems generally, if desired.

With the foregoing complete disclosure, it is thought that a further detailed description ofthe operation would only be superfluous, and while it will be understood that I do not make any broad claims to the dctachable coupling up of a dry closet container to a vent pipe generally, at the same time, I do not limit myself to the exact details as set forth, excepting as come within the terms of the ensuing claims, as viewed in the light of the specification, contemplatin a fair range of equivalents.

v at I do claim as new and patentable might be employed,

1. In ventilated dry closets, of the type wherein the usual container receptacle is provided with a foul air outlet adapted for communication with a vent pipe, the employment of coupling means, embodying a separable Ventilating conduit between 'said foul air' outlet and said vent pipe, comprising a cylindrical member projecting laterally from said vent pipe, the forward end thereof being cut-away on its top to form an upwardly concave receiving tongue of a lower coupling element, and a reversely disposed associated member, said foul air outlet, having a cylindrical portion and an underneath cut-away forward portion, providing an upwardly convex seating tongue of an upper coupling element, said members being complementally proportioned and functioning, in readily attachable and detachable relation, to provide for a snug interunion therebetween, substantially as described.

2. In ventilated dry closets, the combinahaving a foul for communication with a vent pipe; of a base standard, adapted to be mounted in line with said -vent pipe, having a hollow cylindrical head, the forward portion of said cylindrical head being cutawayvto provide a lower enlarged vertical slit extendingto the the whole providing a clamping head; an elbow extended jectin upwardly therethrough, into connecand with its lateral arm projecting freely through said enlarged slot; means for tighteningV and loosening said clamping head around the vertical arm vof said elbow; andcoupling means between "said lateral arm, as a coupling element, and `the foul air outlet of said container, substantially as described.

extending fromv 3. In ventilated dry closets, the combination with the usual container having a foul air outlet adapted for communication with a vent pipe; of a base standard, adapted to be mounted in line with said vent pipe, having a hollow cylindrical head, the forward portion of which is cut away to provide a lower enlarged vertical slot terminating in a slit extending to the top of the head and provided with contiguously disposed vertical ears; an elbow extending through said head, with its vertical arm projecting upwardly therethrough, into connection with said vent pipe, and with its lateral arm projecting freely through said enlarged slot, the forward end of said lateral arm being cut-away on its top to provide an upwardly concave Copies of this patent may be obtained for ve cents each, by addressing receiving tongue of a lower coupling element; clamping means for said vertical ears; an u per coupling element, extending from the oul air outlet of said container, having a cylindrical portion and an underneath cut-away forward portion providing an upwardly convex seating tongue; and a pin and hole interlocking connection between the tongue portion of one member and the cylindrical portion of the other, said couplin elements being complementally proportioned, and the whole construction and combination functioning, substantially as described.
